The heavy duty series 2A pneumatic cylinders described in this catalogue are of all-steel construction and are based on the Parker series 3L hydraulic range – see catalogue HY07-1130. They are exceptionally robust and are ideally suited for applications in steel mills, foundries, aluminium smelting plants or other arduous environments where normal light duty aluminium cylinders are not sufficiently durable. In addition to the standard cylinders featured in this catalogue, 2A cylinders can be designed to suit customer requirements. Our engineers will be pleased to advise on unique designs to suit specific applications.

Non-Lubricated Rod Seals

Gland seal life is maximised by manufacturing piston rods from precision ground, high tensile carbon alloy steel, hard chrome plated and polished to 0.2mm max. Piston rods are induction case hardened to Rockwell C54 minimum before chrome plating, resulting in a dent-resistant surface.

For non-lubricated air cylinders, rod seals with special rounded sealing lips are supplied as standard. Specify series 2AN (see pages 34-35).

4 Cylinder Body

The surface of the cylinder bore is finished to minimise internal friction and prolong seal life. The bore of the cylinder is hard chrome-plated to prevent corrosion and extend the life of the cylinder.

2 Rod Gland

The rod gland, complete with rod seals, can easily be removed without dismantling the cylinder, so servicing is quicker – and therefore more economical.

5 Cylinder Body Seals

3 Rod Seals

To ensure that the cylinder body remains leak free, even under pressure shock conditions, Parker fits pressure-energised body seals.

The serrated lipseal has a series of sealing edges which take over successively as pressure increases, providing efficient sealing under all operating conditions. On the return stroke the serrations act as a check valve.

6 Piston

Lipseal pistons are fitted as standard to 2A cylinders. All pistons are of one-piece type, and feature wide bearing surfaces to resist side loading. Long thread engagement secures the piston to the piston rod and, for additional safety, the piston is secured by thread-locking adhesive and a locking pin.

The double lip wiperseal acts as a secondary seal, cleaning the rod on the return stroke. Its outer lip prevents the ingress of dirt into the cylinder, extending the life of gland and seals.

7 Cushioning

End of stroke deceleration is available by using straight cushions at the head and cap – see page 41 for details. The head and cap end cushions are self-centring. The polished cap end spear is an integral part of the piston rod.

8 Floating Cushion Bushes & Sleeves

Cushioning is provided by the use of a floating cushion sleeve at the head end of the cylinder, and a floating cushion bush at the cap end. The use of a check valve in the head and lifting of the bronze cushion bush in the cap, provides minimum flow restriction at the start of the return stroke. This allows full pressure to be applied over the whole area of the piston, to provide full power and fast cycle times.

Design Features and Benefits


9 Cushion Adjustment

Piston Seals


Needle valves are provided at both ends of the cylinder for precise cushion adjustment, and retained within the head and cap so that they cannot be inadvertently removed. The cartridge type needle valve illustrated below is fitted to cylinders of up to 63.5mm (21/2”) bore – see page 42.

Lipseal Pistons – A Lipseal piston is fitted to 2A cylinders as standard. It offers a wide piston surface which reduces bearing load, and is suitable for speeds of up to 0.5m/s. Fully dynamic and self-compensating seals allow for variations in pressure, mechanical deflections and wear. Non-Lubricated Pistons – For non-lubricated air cylinders, lipseals with special rounded sealing lips are supplied as standard. Specify Series 2AN (see pages 34-35).

Seal Groups

Parker offers two classes of seals for 2A and 2AN (nonlubricated air) cylinders:

10 Check Valve

A check valve is provided at the head end of the cylinder, providing minimum flow restriction at the start of the return stroke. This allows full pressure to be applied to the annular area of the piston, permitting faster cycle times.

Group 1 Seals are standard and are suitable for air or nitrogen. The temperature range for Group 1 seals is -20°C to +80°C. Group 5 Seals are made from fluorocarbon elastomers and extend the working temperature for 2A cylinders from -15°C up to 150°C, or 204°C with reduced life. For non-lubricated air cylinders in high temperature applications, please refer to page 35.

Special Designs

Parker’s design and engineering staff are available to produce special designs to meet customer’s specific requirements. Alternative sealing arrangements, special mounting styles, different bores and rod sizes are just a few of the custom features which can be supplied.

Double rod cylinders employ two separate piston rods, with one screwed into the end of the other within the piston rod assembly. As a result, one piston rod is stronger than the other. The stronger rod is identified by the letter ‘K’ stamped on its end.

Combination Rods

Double rod cylinders with rods of differing rod diameters are also available. Please contact the factory for details.

Cushioning

Double rod cylinders can be supplied with cushions at either or both ends. Cushioning requirements should be specified by inserting a ‘C’ in the ordering code – see page 47. Double rod cylinders that require cushioning are supplied with floating cushion sleeves at both ends.

All dimensions apply to rod no. 1 only. For alternative rod sizes, please consult the factory.

Style 9 Rod Ends

If a stroke of less than 25mm on bore sizes up to 82.6mm (31/4”), or a stroke of less than 100mm on bore sizes of 101.6mm (4”) and over, is required, where Style 9 rod ends are required at both ends, please consult the factory.

Accessories


Accessory Selection

Load Capacity


Accessories for the rod end of a cylinder are selected by reference to the rod end thread, shown on pages 20 and 30, while the same accessories, when used at the cap end, are selected by cylinder bore size. See tables of part numbers below and on the following pages.

The various accessories on these pages have been load rated for your convenience. The load capacity in kN is the recommended maximum load for that accessory based on a 4:1 factor of safety in tension. (Pivot pin is rated in shear). Before specifying, compare the actual load or the pull force at maximum operating pressure of the cylinder with the load capacity of the accessory you plan to use. If the load or pull force of the cylinder exceeds the load capacity of the accessory, please consult the factory.

Pivot Pin Diameters – Style BB To obtain the same diameter of pivot pin at the rod end and cap end of a style BB clevis-mounted cylinder fitted with a rod clevis or plain rod eye, a no. 1 rod should be specified.

Rod and Cap End Accessories

Accessories for the 2A cylinder comprise: Rod End – rod clevis, eye bracket and pivot pin – plain rod eye, clevis bracket and pivot pin Cap End – eye bracket for style BB mounting

Ordering Information

Increased market demand and Parker’s continuous research and testing efforts inspired the development of the Series 2AN Non-Lubricated Air Cylinder, suitable for use with filtered air.

To order a Non-Lubricated Air Cylinder, specify Series 2AN. See page 47 for the ordering code.

Available Bore and Rod Sizes

These cylinders are designed to operate in environments where it is not possible to add lubrication to the compressed air entering the cylinder. Certain packaging and assembly operations, food environments, and microprocessor chip manufacturing are typical examples of applications where the exhausting of oil into the environment is not desirable.

The following bore and rod sizes are available with Series 2AN cylinders. For all other sizes, please contact the factory.

Available in bore sizes up to 304.8mm (12”) diameter and rod diameters up to 63.5mm (21/2”), the Series 2AN cylinder features rounded lip rod and piston seals.

Rounded Lipseal The rounded sealing lip glides over lubricant film instead of scraping it off, and the increased heel thickness and outer lip extension improve stability and resist rolling. The use of the rounded lipseal reduces friction, increases life and eliminates the need for added lubrication.

Design Features and Benefits For the standard features shown above, please see pages 4 and 5. For available bore and rod sizes, please see table opposite.

127.0 (5")

Benefits of the 2AN Series cylinder include long seal and bearing life and, since no oil is added through the use of lubricators, no oil is expelled into the atmosphere with the exhaust air as the cylinder strokes. In addition, the use of nonlubricated air results in lower overall operating costs.

152.4 (6")

With the exception of fluorocarbon elastomer seals, and unless otherwise stated, all modifications available with Series 2A Cylinders are also available with Series 2AN cylinders.

203.2 (8")

Operating Temperatures

254.0 (10")

The temperature range for Series 2AN cylinders with Group 1 seals is -20°C to +80°C. Group 5, high temperatures seals, are suitable for operating temperatures between -15°C and +150°C.

Repairs

Although 2AN cylinders are designed to make on-site maintenance or repairs as easy as possible, some operations can only be carried out in our factory. It is standard policy to fit a cylinder returned to the factory for repair with those replacement parts which are necessary to return it to ‘as good as new’ condition. Should the condition of the returned cylinder be such that repair would be uneconomical, you will be notified.

Ordering Information

To order a non-lubricated air cylinder, specify '2AN' in the order code on page 47.

Mounting Information


Mounting Styles

Foot Mountings and Thrust Keys


The notes which follow provide information for use in specific applications and should be read in conjunction with the information given on page 7.

Extended Tie Rods

The turning moment which results from the application of force by a foot mounted cylinder must be resisted by secure mounting and effective guidance of the load. A thrust key modification is recommended to provide positive cylinder location.

Cylinders with extended tie rod mountings TB and TC are supplied with an additional set of mounting nuts of the appropriate grade for securing the cylinder to the machine member. For style TD, tie rods extended both ends, two additional sets of mounting nuts are supplied. In such applications one end is used for mounting and the opposite end to support the cylinder, or to attach other machine components.

Thrust key mountings eliminate the need for fitted bolts or external keys on Styles C, F and G side mounted cylinders. F The gland retainer plate is extended below the nominal mounting surface to fit into a keyway milled into PD the mounting surface of the machine member. See PA Integral key ‘Mounting Modifications’ in FA the order code, page 47.

The standard tie rod extension for cylinders with mounting style TB, TC and TD is shown as BB in dimension tables. Longer or shorter extensions can be supplied.

Cylinders may be ordered with extended tie rods in addition to another mounting style. The extended tie rods may then be used for mounting other systems or machine components.

Bore Ø

Flange Mounted Cylinders

The diameter of the rod gland extension (B), pages 20 and 30, at the head end can be used as a pilot to locate the cylinders in relation to the machine. After alignment has been obtained, the flanges may be drilled for pins or dowels to prevent movement.

F Nominal

Pivot pins are supplied with style BB cap fixed clevis mounted cylinders and style BC cap detachable clevis mounted cylinders, with the exception of 1” bore sizes, which feature a single tang pivot – see page 16.

1 G mounting is not available with a thrust key on 25.4mm (1”) bore cylinders.

Tie Rod Supports

Trunnion Mounted Cylinders

To increase the resistance to buckling of long stroke cylinders, tie rod supports may be fitted. These move the tie rods radially outwards and allow longer than normal strokes to be used without the need for an additional mounting.

Trunnions require lubricated pillow blocks with minimum bearing clearances. Blocks should be aligned and mounted to eliminate bending moments on the trunnion pins. Self-aligning mounts must not be used to support the trunnions as bending forces can be set up. An intermediate fixed trunnion mounting can be positioned to balance the weight of the cylinder, or it can be located at any point between the head or cap to suit the application. The position of the trunnion is fixed during manufacture and its location must be specified at the time of order.

Bore Ø

Foot mounted cylinders should not be pinned or keyed at both ends. Changes in temperature and pressure under normal operating conditions cause the cylinder to increase (or decrease) from its installed length and it therefore must be free to expand and contract. It must not be pinned or keyed at both ends as advantages of cylinder elasticity in absorbing high shock loads would be lost.

Manifold Ports and Pressure Limitations


Stroke Tolerances

Manifold Ports


Stroke length tolerances are required due to the build-up of tolerances of piston, head, cap and cylinder body. Standard production stroke tolerances are -0.4 to +0.8mm on all bore sizes and stroke lengths. For closer tolerances, please specify the required tolerance plus the operating temperature and pressure. Stroke tolerances of less than 0.4mm are generally impracticable due to the elasticity of cylinders and, in these cases, the use of a stroke limiter should be considered – see page 43.

Side lug-mounted cylinders (Style C) can be supplied with the cylinder ports arranged for mounting and sealing to a manifold surface. Manifold ports are available with both single- and double-rodded cylinders. The ports are drilled and counterbored for O-ring seals which are provided. With these specifications, the mounting is designated Style CM. Please consult the factory.

Mounting Bolts

Parker recommends that mounting bolts with a minimum strength of ISO 898/1 grade 10.9 should be used for fixing cylinders to the machine or base. This recommendation is of particular importance where bolts are placed in tension or subjected to shear forces. Mounting bolts should be torque loaded to their manufacturer’s recommended figures.

Dimensions for rod no. 1 only. For alternative rod sizes, please consult the factory.

Maximum Pressure

The maximum working pressure of 18 bar (250 psi) is based on pure tensile and compressive loadings, without the presence of any bending stresses. Where it is impractical to avoid side loadings, eg: by the use of pivot mountings, please consult the factory giving full details of the application. In many applications, the pressure developed within a cylinder may be greater than the working pressure, due to pressure intensification across the piston and cushioning, eg: in meterout circuits. In most cases, this intensification does not affect the cylinder mountings or piston rod threads in the form of increased loading. If the induced pressure with the no. 1 rod exceeds 18 bar (250 psi), please consult the factory.

inPHorm

For more comprehensive information about pressure limitations for individual cylinders, please refer to the European cylinder inPHorm selection program HY07-1260/Eur. All dimensions are in millimetres unless otherwise stated.

Theoretical Push and Pull Forces Calculation of Cylinder Diameter

caused by the piston rod, the force available on the ‘pull’ stroke will be smaller. To determine the pull force:

Given that the force and operating pressure of the system are known, and that a piston rod size has been estimated taking account of whether the rod is in tension (pull) or compression (push), then the cylinder bore can be selected.

1. Follow the procedure for ‘push’ applications as described above. 2. Using the ‘pull’ table, identify the force indicated according to the rod and pressure selected.

If the piston rod is in compression, use the ‘Push Force’ table below, as follows:

3. Deduct this from the original ‘push’ force. The resultant is the net force available to move the load.

1. Identify the operating pressure closest to that required. 2. In the same column, identify the force required to move the load (always rounding up).

If this force is not large enough, go through the process again but increase the system operating pressure or cylinder diameter if possible. If in doubt, our design engineers will be pleased to assist.

3. In the same row, look along to the cylinder bore required. If the cylinder envelope dimensions are too large for the application, increase the operating pressure, if possible, and repeat the exercise. If the piston rod is in tension, use the ‘Deduction for Pull Force’ table. The procedure is the same but, due to the reduced area

Piston Rod Sizes and Stop Tubes Piston Rod Size Selection

graph by following the horizontal band within which the point of intersection lies. Note that stop tube requirements differ for fixed and pivot mounted cylinders. For cylinders fitted with a stop tube and cushion at the head end, a dual piston arrangement is required – please consult the factory.

The selection of a piston rod for thrust (push) conditions requires the following steps to be carried out: 1. Determine the type of cylinder mounting style and rod end connection to be used. Consult the Stroke Factor table on page 40 and determine which factor corresponds to the application. 2. Using the appropriate stroke factor from page 40, determine the ‘basic length’ from the equation: Basic Length = Net Stroke x Stroke Factor (The graph is prepared for standard rod extensions beyond the face of the gland retainers. For rod extensions greater than standard, add the increases to the net stroke to arrive at the ‘basic length’.) 3. Calculate the load imposed for the thrust application by multiplying the full bore area of the cylinder by the system pressure, or by referring to the Push and Pull Force charts on page 38. 4. Using the graph below, look along the values of ‘basic length’ and ‘thrust’ as found in 2 and 3 above, and note the point of intersection.

If the required length of stop tube is in the region labelled ‘consult factory’, please submit the following information: 1. Cylinder mounting style. 2. Rod end connection and method of guiding load. 3. Bore required, stroke, length of rod extension (dimension W - dimension V – see pages 20 and 30) if greater than standard. 4. Mounting position of cylinder. (Note if at an angle or vertical, and specify the direction of the piston rod.) 5. Operating pressure of cylinder, if limited to less than the standard pressure for the cylinder selected. When specifying a cylinder with a stop tube, please insert an S (Special) and the net stroke of the cylinder in the order code and state the length of the stop tube. Note that net stroke is equal to the gross stroke of the cylinder less the length of the stop tube. The gross stroke determines the envelope dimensions of the cylinder. For accurate sizing, please refer to the European cylinder inPHorm selection program HY07-1260/Eur.

The correct piston rod size is read from the diagonally curved line labelled ‘Rod Diameter’ above the point of intersection. Note: When considering the use of long stroke cylinders, the piston rod should be of sufficient diameter to provide the necessary column strength.

Cushion sleeve

Stop tube

Stop Tubes

Stop tubes prevent the cylinder from completing its full stroke, to provide a separation between the piston and the rod bearing at full extension. The required length of stop tube, where necessary, is read from the vertical columns on the right of the Recommended length of Stop Tube (mm)

inPHorm

When considering the use of long stroke cylinders, the piston rod should be of sufficient diameter to provide the necessary column strength. For tensile (pull) loads, rod strength is unaffected by stroke length. For long stroke cylinders under compressive loads, the use of stop tubes should be considered, to reduce bearing stress. The Piston Rod Selection Chart on page 39 provides guidance where unusually long strokes are required.

For more comprehensive information on the calculation of cylinder bore size required, please refer to the European cylinder inPHorm selection program HY07-1260/Eur.

Cushioning


An Introduction to Cushioning

Cushion Length & Piston and Rod Mass


Cushioning is recommended as a means of controlling the deceleration of masses, or for applications where piston speeds are in excess of 0.1m/s and the piston will make a full stroke. Cushioning extends cylinder life and reduces undesirable noise and pressure peaks.

Where specified, 2A cylinders incorporate the longest cushion sleeve and spear that can be accommodated within the standard envelope without reducing the rod bearing and piston bearing lengths. See table of cushion lengths below. Cushions are adjustable via recessed needle valves.

Deceleration devices or built-in ‘cushions’ are optional and can be supplied at the head end, cap end, or at both ends of the cylinder without affecting its envelope or mounting dimensions.

Oversize Ports

For higher speed applications, oversize ports can be supplied in all bore sizes. Ports one size larger than standard are the maximum that can be accommodated in most heads or caps within the standard envelope dimensions. Certain oversize metric, BSPT or NPTF ports require welded port bosses. The bosses protrude from the side of the cylinder. Port sizes are shown in the tables opposite.

Port Size (BSPP) R1

Note that Y and P dimensions may vary slightly to accommodate oversize ports – please contact the factory where these dimensions are critical.

Manifold Ports

Manifold ports are available on all mounting styles to special order. Side mounted cylinders (Style C) can be supplied with the cylinder ports arranged for mounting and sealing to a manifold surface – see page 37.

Ports and Cushion Adjustment Location

The table below shows standard positions for ports, and cushion adjusting screws where fitted. However, by specifying the position numbers for the desired locations for head and cap ports, many mounting styles can 1 be assembled with ports located at 90° or 180° from standard. In these cases, cushion needle and check valves are 4 2 also repositioned, where fitted, since their relation with the port position does 3 not change.

Where absolute precision in stroke length is required, a screwed adjustable stop can be supplied. Several types are available – the illustration Seal shows a design suitable for infrequent J wrench adjustment at the square uncushioned cap end of a cylinder. Please contact the factory, specifying details of the application and the K min L max adjustment required.

Removable trunnions are available when machine structures or confined space prohibit the use of separate pillow blocks situated close to the cylinder sides. Parker offers a removable trunnion design in 38.1mm to 203.2mm (11/2” to 8”) bore sizes. Mounting diameters and lengths are identical to those in mounting style D and DB for any given bore size. These removable trunnions can be provided on the cap end (see ‘Mounting Modifications’ in the order code, page 47) of Series 2A cylinders with any rod diameter.

Multiple Stroke Positioning

To obtain linear force in one plane with controlled stopping at intermediate points, several designs are available. For three stopped positions, it is common practice to mount two standard single rod Style H cylinders back-to-back, or to use through-tie rods. By extending or retracting the stroke of each cylinder independently, it is possible to achieve three positions at the piston ends. An alternative technique is to use a tandem cylinder with an independent piston rod in the cap section. Please consult the factory for further details.

Single-Acting Cylinders

Standard 2A series cylinders are of the double-acting type. They are also suitable for use as single-acting cylinders, where the load or other external force is used to return the piston after the pressure stroke.

Rod End Bellows

Unprotected piston rod surfaces which are exposed to contaminants with air hardening properties should be protected by rod end bellows. Longer rod extensions are required to accommodate the collapsed length of the bellows. Please consult the factory for further information.

Spring-Returned, Single-Acting Cylinders Series 2A single-acting cylinders can also be supplied with an internal spring to return the piston after the pressure stroke. Please supply details of load conditions and friction factors, and advise whether the spring is required to advance or return the piston rod.

Metallic Rod Wipers

Metallic rod wipers replace the standard wiper seal, and are recommended where dust, ice or splashings might damage the wiper seal material. Metallic rod wipers do not affect cylinder dimensions.

On spring-returned cylinders, it is recommended that tie rod extensions be specified on the cylinder end in which the spring is located to allow the spring to be ‘backed off’ until compression is relieved. Tie rod nuts should be welded to the tie rods at the opposite end of the cylinder, to further assure safe disassembly. Please consult the factory when ordering spring-returned cylinders.

DC Proximity Sensors

These can be fitted to give reliable end of stroke signals. Please consult the factory for further information.

Repairs

Although 2A cylinders are designed to make on-site maintenance or repairs as easy as possible, some operations can only be carried out in our factory. It is standard policy to fit a cylinder returned to the factory for repair with those replacement parts which are necessary to return it to ‘as good as new’ condition. Should the condition of the returned cylinder be such that repair would be uneconomical, you will be notified.

* Seal Groups – Ordering

The part numbers shown in the tables above are for Group 1 seals. For Group 5 seals, substitute a ‘5’ for the ‘1’ at the end of the number sequence. For example, a Group 5 RG gland cartridge kit for a 50.8mm bore cylinder will be RG2AHL205.

Non-Lubricated Service Kits Service kits for 2AN Series non-lubricated air cylinders are shown on page 35.

Service Kits

Group 1 Service Kits contain seals of Nitrile (Buna-N) elastomers. Group 5 Service Kits contain seals of fluorocarbon elastomers.

Parker “Lube-A-Cyl” Air Cylinder Lubricant “Lube-A-Cyl” is intended as a supplement to normal lubrication methods, and is recommended for use during reassembly of air cylinders after servicing. It also helps to prevent damage to static and dynamic seals. This multi-purpose lubricant is available in 110g (4 oz) tubes, part no. 76163.

For further information on seals please refer to page 5.

Tie Rod Torques Please refer to the table on page 37.

Storage Information and Masses Storage

Single Rod Cylinders

When cylinders must be stored for a period of time, the following procedures are recommended: 1. Store the cylinders in an indoor area which has a dry, clean and non-corrosive atmosphere. Take care to protect the cylinder from both internal corrosion and external damage. 2. Whenever possible, cylinders should be stored in a vertical position (piston rod up). This will minimize corrosion due to possible condensation which could occur inside the cylinder, and seal set due to the weight of the piston and rod assembly. 3. Port protector plugs should be left in the cylinder until the time of installation. 4. For long duration storage add a vapour phase inhibitor to both sides of the piston to prevent internal corrosion.

1. Cleanliness is an important consideration, and Parker cylinders are shipped with the ports plugged to protect them from contaminants entering the ports. These plugs should not be removed until the piping is to be installed. Before making the connection to the cylinder ports, piping should be thoroughly cleaned to remove all chips or burrs which might have resulted from threading or flaring operations. 2. Cylinders operating in an environment where air drying materials are present such as fast-drying chemicals, paint, or weld splatter, or other hazardous conditions such as excessive heat, should have shields installed to prevent damage to the piston rod and piston rod seals. 3. Correct alignment of the cylinder piston rod and its mating component on the machine should be checked in both the extended and retracted positions. Incorrect alignment will result in excessive rod gland and/or cylinder bore wear, shortening the life of the cylinder.
